Mechanical fixation using a system in ventilated facade It is the preferred technique for projects using natural stone thanks to its precision, speed, and safety. Screwing stone into a ventilated facade allows for clean, controlled, and highly resistant fixing, even in harsh weather conditions.
Advantages of screwing stone into a ventilated facade
- ✔ Quick assembly and no drying time
- ✔ Precise fixation and absolute alignment control
- ✔ Extremely high resistance to wind loads and thermal expansion
- ✔ Ideal for large format pieces
- ✔ More predictable and stable long-term installation
- ✔ Sustainability and energy efficiency

What if the client prefers to mortar the stone?
Even if you don't opt for a ventilated facade, at CELO Façades we also offer solutions for mortared stone in traditional facade.
However, there is a key aspect that many installers are unaware of:
Spanish regulations require that all mortared facades include retention anchors.
Regulatory compliance (CTE + UNE)
According to Technical building Code (CTE – DB-SE) and the recommendations UNE on adhered cladding, the coatings adhered with mortar They must incorporate mechanical anchors.
These anchors act as security system in case of mortar failure, preventing detachment.
It is not optional: it is a regulatory obligation.
¿Why is it so important?
- Prevents risks of falling pieces to the public road.
- Guarantees the technical responsibility from the installer and the specifier.
- Avoid legal problems and misuse by the end customer.
- It reinforces the distributor's professional image, as in the case of Obramat, by offering safe and compliant solutions.
CELO Façades mortar anchors: certified retention for natural stone

Our mortar anchors for stone:
- GR-AL-2,5
- GR-AM-C10/16
- GR-AM-V
- GR-AM-H
- GR-AM-NEW
- GR-AM-R
Main benefits:
- ✔ They function as a mandatory security system.
- ✔ Corrosion resistant and designed to last.
- ✔ Compatible with multiple thicknesses and formats of stone.
- ✔ Discreet and quick installation.
- ✔ Maximum reliability in case of adhesive or mortar failure.
Thanks to these anchors, even traditional mortared facades can achieve the level of safety and guarantee required by the CTE.
Front safety screw: visible solution for facades with mortar failure pathologies
Although regulations require the installation of retention anchors on all mortared facades, in practice many buildings constructed in previous decades do not. They didn't incorporate them or present pathologies resulting from aging and loss of mortar adhesion.
For these situations, CELO Façades offers a specific intervention solution:
The front safety screw
A retaining element visa, quick to install and highly resistant, designed not for the construction phase, if not then act when the mortar has already failed or risks of detachment are detected.
What is it and what is it for?
The front safety screw is a system chemical and mechanical which is installed from the outer face of the cladding and achieves:
- ✔ Hold the piece of stone or ceramic when the mortar is degraded or has come loose.
- ✔ Prevent landslides in critical areas or areas with a risk to pedestrians.
- ✔ Act as immediate reinforcement on old facades or where anchors were not installed at the time.
- ✔ Allow a localized intervention without dismantling the entire facade.
It is a solution of Repair and Maintenance, designed for buildings that already show symptoms such as:
- Movement or dancing of pieces.
- Cracks in joints.
- Loss of adhesion detected by technical inspection.
- Cladding that already considers risk of detachment.
Why is this element important?
Because many buildings constructed before the CTE (Spanish Technical Building Code) did not include safety anchors. Over time, the mortar loses its properties and can fail. The front safety bolt allows for:
- Act preventivelypreventing damage and accidents.
- Extend the useful life cladding without the need for major construction work.
- Ensure technical compliance under rehabilitation work.
It is a key component for communities, maintenance providers, and technicians seeking a solution fast, visible and certified to reinforce existing cladding.
